5836 7469 8251 6293 4172
If all the odd digits of each number are decreased by 1 and all the even digits of each number are divided by 2 then the even numbers thus formed are arranged in descending from left to right and on the right of these all odd numbers are arranged in ascending order then which of the following numbers will be in the middle of the sequence?
Options
- A3186
- B4172
- C3182
- D8251
Correct answer
C. 3182
Step-by-step solution
We have,
The given sequence = 5836 7469 8251 6293 4172
After subtracting 1 from all the odd digits of each number and dividing all the even digits of each number by 2, we get:
4423 6238 4140 3182 2061
Now, arranging all the even numbers in descending order from left to right, we get:
6238 4140 3182
After arranging all the odd number in ascending order on the right of above numbers, we get:
6238 4140 3182 2061 4423
The, number in the middle of the sequence is ‘3182’.
Hence, the correct answer is option C.
